Theipresentinvention relates to a screen sash formed of all metal partsincluding side rails, each of which is formed from a single sheet ofmetal and a plurality of clip strips, each of which is formed from asingle sheet of metal for holding the screen foraminous sheet inengagement with the rails.

Another important object of the invention lies in the formation of ascreen sash of this nature which will be of a strong and durable rigidstructure comparatively inexpensive to manufacture, and thoroughlyefficient and reliable in use With the above and numerous other objectsin View as will appear as the description proceeds, the inventionresides in certain novel features of construction, and in thecombination and arrangement of parts as will be hereinafter more fullydescribed and claimed.

In the drawing Figure 1 is a fragmentary inside elevation of the screensash embodying the features of my invention, I

Figure 2 is a sectional View through one rail thereof, and

Figure 3 is a fragmentary detail perspective View of one of the clampingclips.

Referring to the drawing in detail it will be seen that the letters Aindicate the four rails of the sash which are secured together in anysuitable or pref-erred manner. These rails are of practically the sameconstruction as far as the essence of the invention is concerned andvary practically only as to their length. A detail description of one ofthe rails, therefore, will suffice to obtain a clear understanding ofall four.

Referring to one of the rails in detail it will be seen that the numeral5 denotes the outside plate. This rail is formed from a single sheet ofmetal bent along parallel spaced longitudinal dimensions to form theplate 5 and this plate at-one end merges into an overhanging extension 6in spaced parallelism thereto. At the other edge the plate 5 is extendedand bent over upon itself as at 7 and the portion 7 is merged into aplate 8 extending at right angles to the plate 5 and merges into a rightangular extending plate 9 which in turn merges into a plate 10 disposedat oblique angles to the plates 9 and 5, and merges into a portion 11lying flat along a portion of the plate 5 and merging into a portionoverlying the portion 6 as is indicated at 12, said portion 12 beingextended-around thefree edge ofthe portion 6.

Associated with each rail is a clamp clip C for holding the edges of theforaminous screen sheet 14: in engagement with the rails. Each clip C isformed from a single sheet of material to provide a plate 15, one end ofwhich merges into an acute extension .6

which in turn merges into an obtuse extension 17 extending at an acuteangle to the plate 15. The extension 17 merges into .an acute extension18 disposeduin spaced parallelism to the plate portion 15 and beingdisposed between said plate portion 15 and the extension 17. The plateportion 15 is adapted to engage the other surface of the plate 5 whilethe extension 18 is adapted to engage the surface of the foraminousscreen sheet 14:.

From the above detailed description it Will be seen that the foraminoussheet of screen material may be efficiently attached to the rails of thesa-sh in a reliable man- The present embodiment of the invention hasbeen disclosed in detail merely by way of example since in actualpractice it attains the features of advantage enumerated as desirableinthe statement of the invention and the above description. It will beapparent that changes in the details of construction and in thecombination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages. 7

Having thus described theinvention, what I claim as new and desire tosecure by Letters Patent is In a window screen frame construction, arail formed from a single sheet of metal bent along spaced parallellongitudinal dimensions to form an inside plate which merges at one edgeinto an extension, said extension merging into an overhanging extension, said overhanging extensionmerg ing into a plate disposedperpendicularly to the first plate, said second plate merging into athird plate extending perpendicularly therefrom, said third platemerging into a l allel spaced longitudinal dimensions to form a platehaving one edge merging into an acutely disposed extension, saidextension of i the clip merging into a second extension acutely disposedto the plate of the clip, 1

said second extension of the clip merging into a third extensiondisposed parallel with the plate of the clip.

In testimony whereof I affix my signature.

OSCAR VENDAL NELSON.
